mod_fileuploader
Upload files using a parallel web worker.
This module provides a web worker and server logic to quickly upload files.
The web worker sends files in 128KB parts to the server, the server recombines all parts to a single file. The web worker is using multiple parallel uploaders to make optimal use of the available bandwidth.
Files are sent to the webworker on the topic model/fileuploader/post/new:
let f = document.getElementById("upload_file").files[0];
let msg = {
files: [
{
name: "resultname", // The name used in the ready message
upload: "WZkhXoaMwrK2StUHmdpp", // Unique name to register the upload process. It's generated by the server if undefined
file: f // Must be a File object
}
],
start_topic: "bridge/origin/foo", // Receives the upload metadata when the upload starts
ready_msg: {
foo: "bar", // Anything you want to send if all files are uploaded
files: [] // This will be set by the worker
},
ready_topic: "bridge/origin/foo/bar",
progress_msg: {
form_id: "some-element-id",
is_auto_unmask: true,
percentage: 0 // Will be set by the uploader, 100 when ready
},
progress_topic: "zotonic-transport/progress"
};
cotonic.broker.publish("model/fileuploader/post/new", msg);
The files received with the ready_msg on the ready_topic will be:
{
name: "resultname", // Name provided in the upload
upload: "WZkhXoaMwrK2StUHmdpp" // Unique name to use with z_fileuploader:status/1
}
An upload can be canceled by publishing the topic model/fileuploader/post/delete/+name,
where the name is the unique name generated by the server.
